dunno. what *do* you want?
if you want to access the dictionary members you just
created, use dictionary syntax:
print mydict["one"], mydict["two"]
if you want to create variables in the local namespace
on the fly, you're obviously trying to emulate some other
programming language (Tcl?) in Python. that's usually a
rather bad idea.
(there are ways to create variables on the fly, but they're
all rather obscure and not very efficient -- so you don't really
want that. but sure, if you can give me a very good reason...)
